DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the structure of a groove for fitting a dowel on a shelf, and more particularly to a structure for preventing the shelf from being displaced or disengaged not only against a downward force but also a forward and backward and upward force. A groove for dowel fitting on a shelf plate that effectively prevents, and thus provides good positional stability even during transportation, shaking such as an earthquake or other vibration, or careless handling such as flipping up the shelf. Related to the structure.

[0002]

2. Description of the Related Art In general, movable shelves used for hanging cabinets for kitchens, cupboards, storage furniture, office cabinets and the like are characterized in that their height can be adjusted. This adjustment refers to a mode in which the upper and lower positions of the support dowel are changed, and a shelf board is placed thereon. As described above, since it is basically mounted on the support dowel from above, first of all, there is no defense against upward force from below, and there is anxiety that it will come off during strong vibration or careless handling. Remains. In addition, as for the packing form, when it is simply set on a cupboard during transportation or the like, it is dangerous to remove it. Therefore, it is not usually set in a cupboard, and a separate packing material is applied and fixed. Under such circumstances, there is a demand for a movable shelf that can be easily fixed and can be easily adjusted vertically.

On the other hand, the manner in which the conventional shelf board is supported by the support dowels is specifically described as follows. First, the basic mode of the movable shelf, which has been most frequently used in the past, is that a simple dowel fitting notch 500 is provided in the small end face 110 of the shelf board 100 as shown in FIG. Is what you do. In another embodiment shown in FIG. 11, the dowel fitting notches at the front and rear of the embodiment shown in FIG. 10 are replaced with one wide notch 500. That is, the two supporting dowels 600 may be sandwiched between the front and rear ends of one wide dowel fitting notch 500, or the shelf 100 may be sandwiched between the back plate 700 and the supporting dowel 600 to fix the shelf 100 in the front-rear direction. It is assumed that.

[0004] However, any of these conventional embodiments is completely vulnerable to an upward external force applied from the lower side of the shelf 100, so that vibrations during transportation, earthquakes or the like, or carelessness are required. At present, inconveniences such as displacement and detachment of a shelf board are frequently caused by an external force including an upward component due to handling or the like.

SUMMARY OF THE INVENTION In view of the above situation, according to the present invention, the shelf can be easily fixed to the supporting dowel and can be easily removed, so that the vertical position of the shelf can be freely adjusted. While retaining the function as a movable shelf that can be
Effectively prevents the displacement and detachment of the shelf board not only for the downward working force but also for the front and rear and further upward working force,
Therefore, the shelf can be provided with good positional stability, and it is excellent in both convenience and safety, even in the case of transportation, shaking such as an earthquake or other vibration, or careless handling such as flipping the shelf. It is an object of the present invention to provide a structure of a dowel fitting groove.

[0005]

As a result of various studies on solving the above problems, it has been found that the object can be effectively achieved by providing a specific dowel fitting groove.
That is, the present invention has an opening on the back surface of the shelf board on each of the left and right edge faces of the shelf board, and is inclined in the upper oblique direction from the opening, and extends in such a manner that the edge face side is open. It is a shelf board provided with at least one dowel fitting groove formed.

[0006] As a typical mode of the dowel fitting groove provided in a manner inclined in the upper oblique direction, both upper and lower sides forming the dowel fitting groove are immediately above the position of the opening on the back surface of the shelf board. In addition to those formed in an obliquely inclined manner, only one of the upper and lower sides is formed in the same manner as described above, and the other is substantially upward from the position of the opening on the back surface of the shelf. A dowel-fitting groove formed vertically and then inclined in the upper oblique direction is also a preferred embodiment.

The dowel-fitting groove may be extended obliquely in the upper side in an oblique direction.
A mode in which the shelf extends from the back of the shelf to the front of the shelf is particularly recommended. In addition, it is desirable that the dowel fitting groove is provided with a position fixing protrusion described later for improving the positional stability of the fitted support dowel.

Further, as another aspect of the present invention, two opening portions opened at a predetermined interval on the back surface of the shelf board are communicated with the left and right edge faces of the shelf board, respectively, and the edge face side is opened. The groove of the inverted U-shaped dowel fitting of the above aspect is at least one.
The present invention also provides a structure of a dowel-fitting groove of a provided shelf board. The shape of the upper side of the partition partitioning the two openings of the substantially inverted U-shaped dowel fitting groove is preferably formed in an upwardly concave shape, and the upper side of the substantially inverted U-shaped dowel fitting groove is preferably formed. In a preferred embodiment, a downward concave portion for dowel positioning is formed at the center of the top. Further, any of the dowel fitting grooves may be provided in a component attached to the left and right small end faces of the shelf.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is a perspective view showing a typical mode of the structure of the dowel fitting groove of the shelf board of the present invention. A dowel fitting groove unique to the present invention is provided on each of left and right edge faces 110 of the shelf board 100 (in FIG. 1, the shelf board is a partially cut-away view and the left edge face is not shown). 200 are provided. That is, the dowel fitting groove 200 is
0 has an opening 210 in the back surface 120 thereof.
, And extends in a manner in which the front end face 110 side is open. The top portion does not penetrate through the surface 130 of the shelf 100 and extends so as to stop at a position in front thereof. Further, the depth of the dowel fitting groove 200 in the left and right direction of the shelf board may be set to an appropriate size according to the length of the fitting portion of the support dowel 600. When the shelf 100 is supported by the supporting dowel 600 by providing the dowel fitting groove 200 obliquely in the upper oblique direction as described above, the opening 210 of the dowel fitting groove provided on the back surface 110 of the shelf 100 is provided. To the position of the support dowel 600,
Next, by slightly shifting the shelf along the inclination direction of the dowel fitting groove 200, the supporting dowel 600 can be easily fitted into the dowel fitting groove 200, and the shelf 100 can be supported by the supporting dowel 600.

The dowel fitting groove 200 extends obliquely upward and obliquely from the opening 210 of the back surface 120 of the shelf board 100. In this case, a mode in which the sheet is extended is preferably adopted. Generally, the shelf board 100
Most of the external force from the lower side to the upper side, which is applied to the shelves, is an inadvertent flip-up at the front portion of the shelf board due to carelessness. Therefore, by arranging the dowel fitting groove 200 such that the inclination direction of the dowel fitting groove 200 is gradually positioned from the back of the shelf M to the front of the shelf N as it goes upward as described above, the front of the shelf board 100 faces upward from below. When an external force of
The shelf 100 is momentarily very small,
The play gap between the lower end of the dowel and the lower side 220 of the dowel fitting groove 200 is flipped up, but at the next moment, the two contact each other, and the resistance of the support dowel 600 fixed to the shelf side plate causes The plate 100 receives the reaction force, and the shelf 1
00 can be effectively prevented from coming off or shifting. More specifically, in the case where the front of the shelf 100, which is the majority of cases, is flipped up, the shelf 100 rotates upward with the end back end as a fulcrum. This causes the shelf board 100 to come off due to displacement.

Accordingly, in order to prevent the shelves 100 from coming off, the rotation of the shelves 100 may be prevented. To this end, the lower side of the dowel-fitting groove 200 is formed by arranging the dowel-fitting groove 200 such that the inclination direction of the dowel-fitting groove 200 is gradually positioned upward from the shelf back M to the shelf nearer N as described above. The reaction force from the supporting dowel 600 acting on the part 220 is applied to the lower side part 220 as vertically as possible to effectively prevent the rotation of the shelf board 100 and effectively prevent the shelf board 100 from coming off. Can be. From this perspective,
It is particularly preferable that the inclination angle at which the dowel fitting groove 200 extends is generally in the range of 25 to 60 degrees, particularly 30 to 45 degrees. If the value exceeds the upper limit of this range, there is a problem in effective rotation prevention of the shelf plate 100 and simple upward splash prevention. If the value is less than the lower limit, the work of fitting and supporting the shelf plate 100 to the support dowel 600 is required. There is a tendency to be troublesome.

The dowel fitting groove 200 of the present invention has at least one
One is provided. As shown in FIG. 4 showing one embodiment of the present invention opposite to the edge 110 of the shelf 100, the shelf 10
In the embodiment in which the dowel fitting groove 200 of the present invention is provided near the front end of the shelf 0 and the dowel fitting groove 400 extending almost vertically upward as in the conventional case is provided near the back end of the shelf.
This is effective for preventing rotation before the shelf. In this embodiment, the work of fitting and supporting the shelf board 100 to the supporting dowel 600 is performed by first fitting the supporting dowel on the front side of the shelf into the dowel fitting groove 200 unique to the present invention, and then substantially vertically upward. The supporting dowel on the back side of the shelf is fitted into the dowel fitting groove 400 extending to the bottom.

Further, as shown in FIG. 1, the present invention is applied to the left and right fore-edge surfaces 110 of the shelf plate, two at a time, ie, one near the front end of the shelf and one near the rear end of the shelf. In a mode in which the unique dowel fitting groove 200 is provided, it is possible to effectively prevent not only the front of the shelf plate 100 but also the relatively large depth of the shelf plate from being flipped up. FIG. 2 is an enlarged view of a portion of the dowel fitting groove 200 in FIG. FIG. 3 is a reference drawing showing another embodiment and corresponds to FIG.

As shown in FIG. 3, the dowel fitting groove extending obliquely in the upper oblique direction in the present invention has a lower side 220 and an upper side 230 forming the dowel fitting groove 200, both of which are shelf boards. In addition to a mode that is formed in a mode in which it is inclined in the upper oblique direction immediately from the position of the opening 210 on the back surface 120 of the 100, a mode illustrated in FIG. That is, of the upper and lower sides forming the dowel fitting groove 200, the lower side 220 is formed in such a manner that the upper side 230 is immediately inclined obliquely upward from the position of the opening 210 on the back surface 120 of the shelf board. This is a form in which it extends almost vertically upward from the position of the opening 210 on the back surface of the plate, and then is inclined in the upper oblique direction. The dowel-fitting groove 200 having such a configuration facilitates the work of supporting the dowel 600 to be fitted into the dowel-fitting groove 200 when the angle of inclination of the dowel-fitting groove extending is designed to be small. There are advantages.

Generally, in the present invention, the dowel fitting groove extending in the inclined direction is provided so that the central axis in the longitudinal direction of the dowel fitting groove extends substantially obliquely upward. Good.

FIGS. 5 and 6 are enlarged views of the dowel fitting groove 200 in the present invention. As shown in these drawings, in order to improve the positional stability of the support dowel 600 in a state where the support dowel 600 is fitted near the upper end of the dowel fitting groove 200, the dowel fitting groove 2 is formed.
The mode in which the position fixing protrusion 240 for preventing unnecessary lowering of the support dowel 600 is attached to the upper side 230 and / or the lower side 220 forming the 00 is particularly preferably adopted as necessary. You. FIG. 5 shows the upper side 230 and FIG.
Shows an aspect in which the position fixing protrusions 240 are attached to the lower side 220, respectively. These position fixing projections 240
When the support dowel 600 is positioned near the upper end of the dowel fitting groove 200, the protrusion is a projection having a height that allows the support dowel 600 to pass over the portion where the position fixing protrusion 240 exists and It is necessary to have a height that prevents unnecessary downward movement of the position.

FIG. 7 is a reference drawing of another embodiment showing an enlarged portion of the dowel fitting groove 200. As shown in FIG. As shown, the dowel fitting groove 200 is
Is extended obliquely upward from the opening 210,
Next, the vicinity of the upper end extends almost vertically upward. Such a mode works more effectively to prevent the shelf plate from being flipped up and also to prevent the lateral displacement.

Further, the present invention also provides a structure of a dowel fitting groove of a shelf board of a mode shown in FIG. 8 which is different from the concept described with reference to FIGS. That is, two opening portions 310a and 310b that are opened at predetermined intervals on the back surface 120 of the shelf plate communicate with the left and right fore end surfaces 110 of the shelf plate 100, respectively.
Further, the dowel fitting groove of the shelf board is provided with a substantially inverted U-shaped dowel fitting groove 300 in a mode in which the front end face side is open. The two openings 310a and 310b are separated by a partition 320 existing between the two openings.

In the embodiment in which the dowel-fitting groove 300 having a substantially inverted U-shape is provided, it is possible to effectively prevent the shelf board 100 from being flipped up by the presence of the partition wall 320 between the openings. That is,
By locating the support dowel 600 above the partition 320, the reaction force from the support dowel 600 acts downward on the partition 320, thereby preventing the shelf board 100 from being flipped up. By forming the upper side portion 321 of the partition wall 320 into an upwardly concave shape, the positional stability of the support dowel 600 is improved, and the upper side portion 321 acts more effectively to prevent the shelf board 100 from being flipped up.

FIG. 9 shows a substantially inverted U-shaped dowel fitting groove 300.
As shown in the figure, a downward recess 331 for dowel positioning is formed at the center of the top of the upper side 330 of the dowel fitting groove 300 as shown in the drawing.
It is also useful for preventing displacement of 00 as well as for preventing displacement. As shown in FIG. 8, each of the horizontally elongated substantially inverted U-shaped dowel fitting grooves 300 is provided near the front end of the shelf on each of the left and right fore end faces 110 of the shelf 100, and near the back end of the shelf. If the dowel fitting groove 400 extending substantially vertically is provided on the upper side, it is sufficiently effective to prevent the shelf board 100 from being flipped up on the near side of the shelf.

[0021]

As described above, according to the present invention, the provision of the unique dowel fitting groove allows the reaction force from the supporting dowel to resist upward or front-rear external force acting on the shelf. Acts to be. Therefore, even if careless handling such as splashing the shelf board, and even during transportation or shaking or other vibrations such as earthquakes, it is necessary to effectively prevent the shelf board from jumping or shifting and obtain good positional stability. Can be. Further, in particular, in the aspect in which the dowel fitting groove is extended obliquely in the upper oblique direction, the support dowel is fitted in the dowel fitting groove, for example, in comparison with the aspect in which the dowel fitting groove is provided in an inverted L-shape. In addition, there is an advantage that the operation for supporting the shelf board is excellent and easy.
